We have one automatic knife a Benchmade.
The top knife is the automatic. The lower two are not automatic but can be opened just as quickly and easily. With the Benchmade Bedlam you just hold back on the blade release to free the blade to close and a flip of the wrist and the blade is opened. With the Spyderco Paramilitary 2 hold in on the compression lock on the back of the handle and do the same. A good feature with both of those if you hold the releases you can let the blades close one handed also.
